In 1998, staff at the St. Louis
Public Library surveyed Missouri libraries and historical societies to identify
organizations that housed map collections and wished to make these collections available
for wider public use. The survey was part of the Missouri Digital Map Project (MODMAP),
funded by the Missouri State Library and the Institute of Museum and Library Services.

Survey responses are divided by organization type: Public,
Academic, and Historical Societies. Information includes the
name of the contact person, current (as of 1998) mailing address, phone number, and email
address. The final column reports the number of maps in the collection and the format of
the holdings record. P means that the organization has some type of paper records.
